| Summary: | Octomeles sumatrana and Anthocephalus chinensis are two non-commercial tree species with future potential
as plantation species in Malaysia. In order to understand the habitat in which such species grow, a study on the species as
well as organisms related to them is crucial. The objectives of this study were to investigate the soil properties in which the
two species grow and the associated mycorrhiza occurring within their rhizospheres. Results revealed that the properties
of rhizosphere soils and the composition of arbuscular mycorrhiza varied with location. Based on the spore count method,
the mean number of spores ranged from 45–142 per 50 g dry soil. The rhizosphere of O. sumatrana at the Niah Forestry
Research Station recorded the highest number of spores. Meanwhile, the most probable number method showed values
ranging from 6.5–16.0 per gram of dry soil, with the highest value recorded for O. sumatrana at the Niah National Park.
A. chinensis showed the lowest values for both methods. Glomus was found to be dominant in the rhizospheres of both
species followed by Acaulospora and Gigaspora. O. sumatrana was found to be a better host plant than A. chinensis in
terms of supporting the sporulation of mycorrhiza. This is believed to be closely related to the ability of the root system to
make the rhizosphere more suitable for reproduction and development of mycorrhiza spores, besides being affected by soil
properties. |
